WIRE-RETAINING DEVICE FOR LO OMS FOR WEAVING PILE FABRlCS.

SPECIFICATION forming part of Letters Patent No. 529,615, dated November20, 1894.

' I Application filedMarch 5,1894- Serial No.502,430. (N model.)

To 60% whom it may concern: I

Be it known that I, HARRY HARDWICK, a

' citizen of the United States. residing in Philadelphia, Pennsylvania,have in ventedcertain Improvements in Wire-Retaining Devices for Loomsfor Weaving Pile Fabrics, of which the following is a specification.

The object of my invention is to provide a loom for weaving pile fabricswith means whereby the production of uniform pile is insured, and thisobject I attain in the manner hereinafter set forth and claimed,reference being had to the accompanying drawings, in wl1ich- Figure 1,is a longitudinal sectional diagram representing sufficient of a loom toillustrate my invention. Fig. 2, is a plan view showing the selvages ofthe cloth and the lateral limits of the warp by dotted lines, andillustrating but one of the pile wires; and Fig. 3, is a perspectiveview of the attatchnient forming the subject of my invention.

In modern looms for weaving Brussels and Irvilton carpets and like pilefabrics, the pile wires are frequently in the form of thin blades whichare intended to stand upright in the row of pile loops and thus governthe height of said loops as well as the width of the same. It will beevident, therefore, that if the pile wire does not maintain the uprightposition from selvage to selvage of the fabric the uniformity of thepile will be seriously af-' fected and in practice this is often foundto be the case, the strain of the pile warp upon the central portion ofthe pile wire causing the twisting of the same so'that the centralportion is bent forward and downward and thus fails to properlydetermine the height and position of the pile loops in this portion ofthe fabric. In order to overcome this objection I use one or moreretainers located between the selvages. of the fabric and adapted toengage with the upper edge of the pile wire and hold the samein theproper ver-,

tical position.

In Figs. 1 and 2 I have shown one of these retainers located midway ofthe fabric, said retainer belng represented at A while B represents thebreast beam of the loom, D the reed, w the pile fabric which is beingwoven, and y the pile supporting wires which are successively introducedin the usual manner in advance of the beating up .point and aresuccessively withdrawn after the fabric has advanced to the properextent.

The retainer A has a hook a for engaging with the last inserted pilewire and projecting forwardly beyond this hook is a finger b preferablyof such length that it will pass through one of the spaces of the reedwhen the latter has been retracted to itsfull extent, so that said reedwill serve to hold the free end of the retainer in properlateralposition at alltimes. The retainer has an arched shank d possessing suchelasticitythat the tongue I) and hook at of the retainer can yieldvertically in order to permit of the passage of a pile wire beneath thetongueand to a position in advance of the hook in beating up, the hookthen springing into engagement with the pile wire so as to mantain thesame in the desired upright position.

The outer end of the retainer A is slotted as shown at f forthereception of a retaining bolt g which is screwed into a bar F mountedupon the breast beam beyond the selvages of the fabric and supported atsuch height that the fabric can pass freely beneath the same. Havingthus described my invention, I claim and desire to secure by LettersPatent- 1. A pile loom, having a pile wire retainer secured to a supportabove the fabric which is being woven, and located between the op-.

posite selvages of r the same so as to engage the body of the lastinserted pile wire to retain the same in upright position, substaningwoven, and apile wire retainer carried by said bar and occupyingapositionbetween the opposite selvages of the fabric, said retainer beinghooked to engage with the last inserted pile wire in order to hold thesame to hold the same in upright position, substan- 10 innprightposition,substantially as specified. tiaiiy as specified.
